How much does astrology play a part to you libra's

Do libra males in general assume how a female is by her astrological sign

Ah, I look at it as a guide, but not the end all be all. Almost everyone I've been with or gone after have never been the sign for me. But most, if not all, have been good breaks and we stay in contact. I like to see the sign just to see the best way to approach. Obviously, everyone is different, but the traits generally line up.

I use it to get a feel on somebody's personality but I try not to get to into it.

Usually when I'm going through a period of introspection, astrology will be a part of the equation.
I thought it was a big part until I realized I could read any signs personality profile and it would fit anybody at any given time.
After coming to this realization - astrology is nothing more than a source of 'pack mentality' when I need it.
